Munster have confirmed the signing of Argentinian hooker Eusebio Guinazu on a four-month contract. He will join the province later in the month subject to obtaining a work permit and passing the normal medical procedures.
This is Munster's second semi-final appearance of the season as they return to 'cup final' mentality, facing the in-form Glasgow Warriors who host their first ever play-off fixture at Scotstoun Stadium.
With their place in the play-offs confirmed, Ulster will give some of their youngsters the chance to shine against a Munster team that are still chasing home advantage in the RaboDirect PRO12 semi-finals.
The Ospreys' failure to win away to Zebre means that Munster are safely through to the RaboDirect PRO12 play-offs, but they are now six points adrift of Glasgow Warriors in the race to secure a home semi-final.
